To all whom it may concern:

Be it known that I, JULIUS Q. GILL, a cltizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented new and useful Improvements in Cooling Compounds for HotJournal Boxes and Processes for Producing the Same, of which thefollowing is a specification.

The lnventlon relates to. a cooling compound for hot boxes, and processfor producing the same.

The object of the invention is the productlon of a compound designed forcooling hot boxes on rallways'and street cars, locomotives and in factany vehicle in which that condition occurs, and adapted when mixed witha heated lubricant of reducing the temperature-ofthe moving parts.

The compound is designed for use in emergency for cooling a hot box andis adapted to be readily applied to the same wlthout removing the heatedlubricant from the journal box. J

This compound consists of a mixture of vegetable oils, such ascorn oiland castor oil, alkali such as caustic soda, soda ash and potash, carbonsuch as ivory black, methyl salicylate, free alkali as carbonates and Inpreparing the cooling compound, a kettle is charged with 100 lbs. ofcorn oil to which is added 50 lbs.'of water. Heat is then applied andthe contents thereof are tlien warmed to approximately 120 F. Then add25 lbs. of, caustic soda solution at 35 degrees Baum and bring the.contents to a boil and continue at a gentle boil until it thickens upand shows dry on a spatula.

Then add to the mixture 5 lbs. of soda. ash

dissolved in 25 lbs. of water and then 'run in 25 lbs. of potashsolution-at 40 degrees Specification of Letters Patent. Patented July18, 1922.

Application filed August 2, 1920. Serial No; 400,634. C

Baum. Now boil thoroughly until the mass has settled low in the kettleand shows" up clear and transparent on the spatulal Now to finish up andfit with alkaline strength, take samples on the spatula, allow them tocool ofi' and test with a drop of phenolphthalein 5% solution. If themix ture fails to react red, add a very small amount of potash at 40degrees B'aum and boil thoroughly and test again. Continue thisoperation until a faintred reaction from the .-phenol hthalein takesplace. 40 lbs. of water are t en added in order to bring the yieldofcompound up to 2% lbs. to the pound of oil. I

During the boiling operation, a portion of the :moisture will have beenevaporated and this is compensated for'by adding .at the finish 1% lbs.of ivory blackmixed with a small quantity of hot water, 2% lbs. ofmethyl salicylate and 23 lbs. of commercial castor oil. The contents ofthe kettle are then thorou hly stirred and a finish test made withpfienolphthalein. If this last test fails to show a red reaction becauseof the castor oil having taken up all the free alkali, the mass shouldbe once more treated with a small portion of potash solution until itshows a faint red reaction at which time the heat ma be shut off and thematerial drawn 01f for s ipment.

What is claimed is: v

1. A cooling compound for hot boxes, which consists of corn oil, castoroil and caustic alkali in such proportion as to form 'soap, a smallamount of free alkali, ivory black, methyl salicylate, and water in suchpro ortion as to constitute more than 50% oft e mixture.

2. A- cooling compound for hot boxes,

, which consists of soap consisting of 35.59% corn oil, .89% castor oiland 6.826% caustic alkali; 534% ivory black, .89% methyl saliv I cylate,.36% free potash, and 55% water.

' 3. The process of cooling hot boxes, which consists in applyingthereto a cooling compound, the constituent ingredients of which arecorn oil and castor oil soaps, free' alkali; ivory black methylsalicylate, and a large proportion oi wate 4. The process of cooling hotboxes, which consists in applying thereto a cooling compound, theconstituent ingredients of which are soap consisting of 35.59% corn oil,.89% castor oil a nd 6.826% caustic alkali; 534% ivory black, 89%methylsalicylate, 36% operation and then adding ivory black, free potashand 55% water. methyl salicylate and castor oil andfinally 5; The hereindescribed process for proadding enough potash to give a faint red re- 10ducing a cooling compound, for hot boxes action with phenolphthalein.

5 and the like, which consists in boiling corn In testimony whereof Ihave hereunto oil and caustic soda and then adding soda afiixed mysignature. ash and water and continuing the boiling JULIUS Q. GILL.
